fairly against the blades 11, rotate the float and connected parts, thuscausing the arms 10 to agitate the liquid in the shell, particularlynearthe bottom, and prevent particles 1 suspended in the liquid fromscttlingupon the bottom of the shell and possibly adher- .ing thereto.

in Figs. 5 and ii the upper end of the tubio lar valve 6 is permancrnlyclosed, and this portion of the valve and Host is guided by a pluralityof lugs or proioctions 12 upon the sides oi the lloat. partiallyunbalanced that is, any pressure within the shell I or any vacuum iiithe outlet 4 will tend to hold the valve ii more sccurely to its scat.

ing of this form oi valve, one or more vcnt or air tubes- 14 areprovided, connected to the body of the valved with their free ends inproximityto the bot tom of thc shell, thus serving in place oi" the armsH] to agitate the liquid in the shell 1, also to remove a portion of theliquid in the shell and to prevent airlocking. The tubes 14 also tend topartially equalize the pressure in tho shell ly and in the outlet 4,thus leaving the valve more sensitive to the action of the float.

In some cases the dill'oronce in iressure hotwcen thc'intorior of theshell and in the outlet 4 is sull'icient, with the abovddescribedequalizing means, to hold the valve to the seat 5 with considerablei'oi'cc. To prevent this from interfering with the operation of thoValve, considerable space is left, between tho ends oi" tho lugslz andthe walls of the float, so that tho top oi tho valve may be moved aboutby tho fluid entering the shell- 1 from the inlet 3, thus rocking thevalve upon its seat and completely releasing the same.

Where the movements of the valve and iloat, especially in thelnst-descnibed form, tend to produce an undesirable amount ol noise, thelugs 12 may be ionmed ol' auysuitable composition and attached to thewall of the shell. Also a composition facing may be provided upon therecess 8 and valvcssoal, 5, as shown in Fig. 3, and, if found desirable,other contact-surfaces may he faced with composition or other suitablemeans em-- played to rrevent metallic contact between the niovab o andstationary parts of my deand in the drawings the prcfcncd forms of Topartially overcome. this tcndcncynml insure the properuir-vcntundorstoml as limiting myself to. the exact term or constructionshown, as various immatorial mmlilications may he nadein my and anoutlet, and means for connecting said l l ing an inclosing shellprovided with an lnlet l l shell in a steam system, in combination withoperated by the liquid as it enters said shell l for agitating theliquid in said shell.
